• Limited lifetime switch hardware warranty
Each EX4200 switch includes an integrated application-specific
integrated circuit (ASIC)-based Packet Forwarding Engine, the
EX-PFE, while an integrated Routing Engine (RE) delivers all
control plane functionality. Based on field-proven Juniper
Networks technology, the Route Engine brings the same level
of carrier-class performance and reliability to the EX4200 line
of Ethernet switches that Juniper Networks routers bring to the
world’s largest service provider networks.
The EX4200 also leverages the same modular Juniper Networks
Junos OS as Juniper Networks router products, ensuring a
consistent implementation and operation of each control plane
feature across an entire Juniper Networks infrastructure.
Architecture and Key Components
The EX4200 switches are single rack-unit devices that deliver a
compact solution for crowded wiring closets and access switch
locations where space and power are at a premium. Each EX4200
supports optional front-panel uplink modules offering either four
GbE ports or two 10GbE ports for high-speed backbone or link-
aggregation connections between wiring closets and upstream
aggregation switches. Uplink modules can be installed without
powering down the switch, enabling users to add high-speed
connectivity at any time or migrate from one uplink type to
the other to deliver the ultimate in flexible, high-performance
interconnectivity.
The EX4200 also features a front-panel LCD that offers a flexible
interface for performing device bring-up and configuration
rollbacks, reporting switch alarm and LED status, or restoring
the switch to its default settings. The LCD also displays a Virtual
Chassis member switch’s chassis “slot number” and Route Engine
status for rapid identification and problem resolution.
Dual rear-panel Virtual Chassis ports enable EX4200 switches to
be interconnected over the 128 Gbps virtual backplane. Switches
deployed in close proximity, such as wiring closets or top-of-
rack data center applications, can be securely connected using a
Virtual Chassis cable and cable lock supplied by Juniper Networks.
In addition, a dedicated rear-panel RJ-45 port is available for out-
of-band management, while a rear-panel USB port can be used to
easily upload Junos OS and configuration files.

technology delivers a high-performance, scalable and highly reliable
solution for data center, branch and campus environments.
